Helmet manufacturers normally keep information about their safety performance under their hats (so to speak). Not this time for AGV. They share information about why the K6 is their safest helmet yet. Click above for our video that explains why, and all the details you need about the Italian brand’s sporty road helmet... Please note: Since we published this video the AGV K6 has been tested by the UK Government's SHARP impact testing programme and achieved the maximum five stars.
